CHEMICAL FIRE-PAIL.

SPECIFICATION forming part of Letters Patent No. 392,353, dated November 6, 1888.

Application filed April 18, 1888. Serial No. 271,064. (No model.)

To aZZ whom it may concern:

Be it known that I, CLARENCE R. MAOOM- BER, a citizen of the United States, residing at Worcester, in the county of NVorcester and State of Massachusetts, have invented certain new and useful Improvements in a Chemical Fire-Pail; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to a chemical fire-pail or to a pail for holding water or a chemical fire-extinguishing liquid; and my invention consists in certain novel features of construction of a fire-pail, as will be hereinafter fully described.

Heretofore fire-pails have been used and have been placed in buildings and on shipboard, designed to be ready for immediate use in case of fire. These pails are filled or partially filled with water, and in most instances have no cover or top, and as a consequence the water in them is evaporated or is used for some other purpose, so that when said fire-pails are required for immediate use, in case of a sudden fire, they are of no value, as they are most always empty or only partially filled.

It is the object of my invention to make a fire-pail, preferablya chemical fire-pail, which, after it is filled with water or chemical fireextinguishing liquid, may be hermetically sealed, so that the liquid cannot, evaporate therefrom, but must remain in the pail for an indefinite period, and consequently be always ready for immediate use, and, further, to hermetically seal the pail in such a manner that the contents thereof may be almost instantly reached to be thrown upon the fire in case it is desired to use the pail for that purpose.

Referring to the drawings, Figure 1 represents a detached section of a chemical fire-pail of my improved construction, and Fig. 2 represents a modified construction.

In the accompanying drawings, 1 is a pail provided with a bail or handle, 2, in any ordinary manner. The upper part of the pail 1 is provided with a screwthread, 3. A cover or disk, 4, of tin-foil, wax paper, or any easilyperforated material, rests upon the top edge of the pail 1. The outer edge, 4, of the cover is preferably turned down to extend over the outer screw-threaded edge, 3, of the pail 1.

Attached to the cover4 is astaple or eye, 7, provided with a button, 8, or other means for securing the staple 7 or equivalent device to the cover 4. A ring or collar, 5, preferably of zinc or other metal, having its lowerpart screw-threaded and its upper part turned in at 5 to extend around the top of the pail 1, is screwed upon the top of the pail, thus securing the cover 4 in place and hermetically sealing the pail 1. The inwardly-projecting rim 5 of the collar 5 serves as a protection for the easily-perforated cover 4 around the edge of the pail, where it is most liable to'be broken or injured.

In case the chemical fire-pail is to be placed where there is a liability or danger of the easily-perforated cover 4 being accidentally broken or injured, I provide a supplemental cover, 6, of tin or other not-easily-perforated material, to extend over the top of the pail, as shown in Fig. 2.

The operation of my chemical fire-pail will be readily understood by those skilled in the art. The pail 1 is first filled, the easily-perforated cover 4 is then placed over the top of the pail, and the ring 5 is then fitted on the top edge of the pail over the cover 4 and screwed into place. In case it is desired to use the pail and to discharge the contents thereof onto a fire, the user thrusts his hand through the easily-perforated cover 4 or tears it open by means of the staple 7 or equivalent device, and through the opening thus made discharges the contents of the pail.

If desired, a cord or chain may extend from the staple 7 and be attached to a hook or similar device, so that when the user takes the pail by the handle 2 to use the same the cover 4 will be automatically torn or broken through without any action on his part, and at the same time the supplemental cover 6, in case one is used, will beremoved.

The advantages of my improved fire-pail will be apparent to those skilled in the art.

I provide a fire-pail which may be hermetically sealed, so that the contents will remain therein for an indefinite period and be always ready for immediate use. At the same time I construct the pail in such a manner that the cover can be easily perforated to allow the contents to escape without taking the time to remove the cover.

The details of construction of some of the parts of my improved fire-pail may be varied 5 somewhat from what is shown and described,

if desired. A ring or washer-packing may be introduced between the ring 5 and the edge of the cover 4,

Having thus described my inventiolmrhat I 10 claim as new, and desire to secure by Letters Patent, is-- 1. The combination, with a pail having the screw-thread 3 upon its upper part,ofan easily-
